# Wan 2.6 R2V Flash

> Fast Wan 2.6 reference-to-video model for subject-consistent generation.

Fast Wan 2.6 reference-to-video model for subject-consistent generation.

## Model Information

| Field      | Description                |
| ---------- | -------------------------- |
| `model`    | wan2.6-r2v-flash           |
| `endpoint` | POST /v1/video/generations |

## Capabilities and Usage

* Requires metadata.input.prompt and reference\_urls. Use metadata.parameters.size, such as 1280\*720; duration is an integer from 2 to 10 seconds.
* metadata.parameters.audio defaults to true. Set false for silent output; on I2V Flash it overrides input.audio\_url.
* Keep model at the root and input/parameters under metadata. Do not copy the Wan 2.7 media schema into Wan 2.6 requests.

Submission creates an asynchronous task. Save the returned MixRoute task ID and poll [Query Video Task](/en/api-reference/endpoint/query-video-task) until a terminal state. Do not resubmit solely because a client times out.
